Improvement in fanning-mills



PATENT CHARLES SAUNDERS, OF CAPE VINCENT, NEW YORK.

IMPROVEMENT IN FANNlNG-MILLS.

Specification forming part of Letters Patent No. 179,732, dated July l1, 1876; application filed May 22, 1876.

To all whom it may concern Beit known that I, CHARLES SAU'NDERS,

of Cape Vincent, Jefferson county, New York,

have invented a new and Improved Fanning- Mill, ot' which the following is a specification:

This invention consists of' an improved feed apparatus; also, an arrangement of chatting, screening, and separating shoes independently of each other, for regulating each according to its needs, and for Working them so as to counteract the shocks of one by the other; and also of adjusting contrivances for regulating the inclination ot' the screens, all as hereinafter described.

Figure l is a longitudinal sectional elevation of my improved tanning-mill, taken in line :t x, Fig. 2; and Fig. 2 is a plan View.

Similar letters of reference indicate corresponding parts.

A is the hopper, in the bottom ot' which isa hole, B, through which the grain falls onto a shoe, C, attached to the chute-board D of the chatting-shoe E, so as to be vibrated by it, and being suspended Aby the cord F, by which it is regulated to vary the feed. G is the screening-shoe, which is constructed, mounted, and operated independently of theshoe H,which is also arranged to work independently ofthe chatting-shoe, thus enabling each shoe to he vibrate-d more or less, as the work demands, and it also allows them to be so operated that the shocks ot' one will counteract those ot' the other.

The shoes E and Gr are worked by the upright crank-shaft I, to which they are connected at opposite sides, so that they work in opposite directions at the same time, and thus neutralize each othcrs shocks. The crankshaft I is connected with the fan-shalt by a pitman, W.

The screening-shoe is supported at the outer end on the cross-bar J, one end of which is made to shift up and down to adjust the inclination laterally, to prevent the grain from tlowing to one side, and the inner end is mounted on vertically-sliding post S, carrying a roller, T, at'its upper end, which post is adjusted by a lever, K, for varying the descent ofthe screen, to make the grain pass ot`t` more or less rapidly. The shoe H is in like manner arranged on the post U and roller V, adjusted by the lever L, to vary its descent or pitch, for the same purpose. This shoe is connected to the cranked rock-shaft M, which is worked, by the. connecting-rod N, from the fan-crank.

The screen G has two sieves, from one of which the grain falls into the spout O, to be carried out at P, and from under the separatorsieve H a spout, Q, discharges the smaller grain lalling through it, while that which passes oli' from the top t'alls into another receptacle. y

Haying thus described my invention, I claim as new and desire to secure by Letters Patentl. The combination, with the hopper' A, having passage B, of the shoe C, connected at the upper end to the vibrating chatting-shoe, and suspended adjustably at the lower end by the cord F, substantially as specified.

2. The combination of lthe vertical crankshaft l, bottom crank-shaft M, connecting-rod N, and pitman W with the independent shaking-screens E G H and the fan-shaft, as and for the purpose set forth.

3. The combination ot' the sliding posts S U, carrying rollers T V, and the levers K L, with the screen-shoes G I, as and tor the purpose set forth.

CHARLES SAUNDERS.
